Are there any studies that show the effectiveness of slt (selective laser trabeculoplasty) performed after an alt (argon laser trabeculoplasty) to treat pigmentary glaucoma? If it is, do you know a physician who has had success?

Last week, Retina Implant, AG, a German developer of subretinal implants for the visually impaired, announced the publication of a peer-reviewed study the technical and clinical results obtained during their first human clinical trial. In the trial, a light-sensitive, externally powered microchip was surgically implanted subretinally near the macular region of volunteers blind from hereditary […]
Iris plateau syndrome is rare and can be hard to manage. The theory is that it’s secondary to anterior rotation of the ciliary body, which is why iridoplasty and iridectomy often don’t fix the problem. Using high definition ultrasound of the anterior segment, researchers showed resolution of this condition by shrinking the the ciliary processes […]
I am a patient with anterior basement membrane dystrophy (ABMD) and am interested to know what my treatment options are.
My 15 yr old daughter has retinopathy of prematurity (ROP) from birth. I read with interest of retinal implants, this week in Germany a guy who has retinal pigmantosa being able to see, albeit shape outlines, a step in right direction. Is there any p…
I have a son of 3 months with a detached retina in both eyes on 5th stage. He had a surgery on 19th oct in his left eye, but I am told there is no hope to restore his vision. i have heard about stem cell treatment of stem cells, and retinal cloning. Can you […]
In March, 2010 I had a Toric Lens implanted in my left eye. Since I have Fuchs Dystrophy, I also needed to have a corneal transplant, which I had done in May,2010. My vision did not improve as well as the doctor expected. I still am experiencing blurry vision. My vision went from 20/70 to 20/50. […]
i would like to know if anyone has heard of stem cells being used to treat central retinal vein occlusion (CRVO). The patient has already had Lucentis injections in both eyes.
By Dr. Ari WeitznerIn Canada, they are doing simultaneous cataract surgery in both eyes. The advantages are obvious- less cost and less downtime for both patient and doctor. Downside? If there is an infection, it may affect both eyes, and the patient is in big trouble, and both the surgeon and patient may never forgive […]
By Dr. Ari WeitznerA good study sponsored by the NEI compared IOL and CL for infantile cataract, and surprisingly, the vision in the two groups were similar. Complications of course were higher for the IOL group. I find this study hard to believe, for when I was a resident, those kids never wore those contact […]
By Dr. Randall WongMany of us just returned from the largest ophthalmic “trade show” in the world. The American Academy of Ophthalmology convened in Chicago last week. This meeting was combined with the Middle East Africa Council of Ophthalmology (MEACO). Perhaps 40 K attended the meeting.
I also attended the 2 day retinal subspecialty meeting which […]
By Dr. Ari WeitznerIn Molecular Vision journal, cataract development in rats was retarded in those who were administered caffeine, presumably by the anti-oxidants bioflavanoids. But I am sure a year from now, the opposite will be found to be true- there is so much conflicting evidence about coffee. And I’m sure one will have to […]
By Dr. Ari WeitznerA clever study in AJO confirms that oxygen is the culprit in nuclear sclerotic cataract. Diabetics with ischemic retinas had much less cataract pre and post vitrectomy compared to diabetic without ischemia. So, although ischemia stinks, the lack of oxygen is why these patients don’t get that kind of cataract. If we […]
By Dr. Ari WeitznerA small study confirmed suspicions that early vitrectomy for vitreous hemorrhage detected retinal tears (almost 50%) missed by ultrasound. Complications of surgery were low (less than 5%). Perhaps it’s time we re-consider our c…
By Dr. Ari WeitznerA small study in AJO demonstrated a nice response to Valtrex in these AZOOR patients. This suggests that the Herpes virus is indeed the culprit. Although AZOOR is rare, a larger, prospective study might be nice.
By Dr. Ari Weitzner A study compared Xalatan/Timolol combination to Travatan and Lumigan/Timoptic combinations. The Lumigan combination lowered the IOP the most (1.7 more than Xalatan, 0.7 more than Travatan). I dread getting an earful from the drug rep…
By Dr. Ari WeitznerAn article in AJO compared Besivance, Azasite (both using DuraSite vehicle) and Cipro when injected into rabbit eye anterior chambers. It seems the Durasite blocks the trabecular meshwork and may be toxic. The authors advise not using these drops after clear corneal surgery unless a suture is placed. I don’t know anybody […]
By Dr. Ari Weitzner An article in Archives demonstrated a much higher rate of progression in visual fields in glaucoma in those patients with an elevated anti-cardiolipin. Many have argued that there is an inflammatory and/or vascular component to glaucoma, and this would buttress that argument. Maybe we should be ordering this test and being a […]
